SPECIFICATION forming part of Letters Patent No. 390,408, dated October 2, 1888.

Serial No. 259,935. (No model.)

To ctZZ whom it may concern:

Be it known that we, ALBERT M. SPAULD- ING, of Floweriield township, in the county of St. Joseph and State of Michigan, and HER- BERT L. CASE, of Bristol Centre, in the county of Ontario and State of New York, have invented a new and Improved Vehicle-Vrench, of which the following is a full, clear, and exact description.

The object of our invention is to provide a new and improved wrench specially adapted for conveniently unserewing the nuts of vehicle-axles for removing` the wheels for lubricating or for other purposes.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinaftenand then pointed ont in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters ot' reference indicate corresponding parts in all the figures.

Figure l is a side elevation of the improve ment as applied. Fig. 2 is a sectional plan view of the same on the line 0c v of Fig. 1. Fig. 3 is a sectional end elevation of the same on the line g/ y of Fig. l, and Fig. tis an enlarged sectional plan view of the jaws and bent bar.

The improved wrench A is provided with the jaws Band C, of which the jaw B is adapted to be secured to a bent bar, D, by means ofa set-screw, B', screwing in the said jaw B and against the spring-bar D,which passes through the said jaw B. The other jaw, C, is held to slide loosely on the spring-bar D, and the two jaws B and C are adj usted toward or from each other on the bent bar D by means of a screwrod, E, screwing into the loosely-sliding jaw C and extending at its smooth end F into the jaw B, as shown in Fig. it. In this part F of the screw E is formed an annular groove, G, into which projects a set-screw, H, screwing into the top of thejaw B. This arrangement permits of turning the screw-rod E in the jaw B and prevents it from falling out ofthe same. Screw-rod E is provided with a milled collar, I, for turning the said screw-rod E, located, preferably, between the two jaws B and C, as The bar D is bent so as to extend at its middle in front of the hub of the vehiclewheel and at its ends between the spokes.

On the ends of the bent bar D are held to slide the arms J and J', extending at right angles to the said bent bar D, and each provided at each end with a recess, K adapted to lit the inner sides of two snecessivespokes, L, of the vehicle-wheel N, held in place on the axle Oby the nut P, on which the said wrench A is to operate. To the middle of the arm J is secured one end of a coiled spring, Q, fastened by its other end on the arm Jand serving to pull the arm J inward tightly on the respective spokes L.

The operation is as follows: Vhen it is desirable to remove the nut P from the axle O, so as to be enabled to take off the wheel N, the operator adjusts the jaws C and B1 to the size ofthe nut l by turning the milled collar I, so that the screw-rod E moves the jaw C, according to the size of the nut l?, toward or from the jaw B, iixed on the bent bar D. The operator then inserts the arm J between two spokes, L, and pulls the bar D until the jaws B and C lit onto the nutl. The operator then bends the other end of the bar D between the spokes and slides the other arm, J, inwardly until it engages the two successive spokes, L, as shown in Figs. l and 2. Vhen the operator new turns the wheel N, the wrench A'turns with it and unscrews the nut l? from the axle O. As soon as the nut l is unscrewed from the axle O the operator can remove the wheel N for lubricating or other purposes.

When the operator desires to place the wheel N on the axle O again, he places the said wheel on the spindle ofthe axle and turns itseveral times, so that the nut P, which is securely held by thejaws B and C of the wrench A, is again screwed on the threaded end ofthe axle O. As soon as the nut P is adjusted as described the operator slides the arm J outward until it is disengaged from the spokes, and the wrench A can now be easily taken ot'f the wheel N. Thus it will be seen that the nut is easily taken oft' 95 or put on thethreaded end of the axle O without being touched by the operator.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent-q iOO l. A vehicle-wrench comprising a bar havl wrenclrhead on the bar between its ends, arms ing a wrench-head between its ends and arms l sliding between their ends onl said bar at opinounted adjustably between their ends on the l posite sides of the wrench-head and at right bar at opposite Sides of the wrenchhead and at right angles thereto, the opposite ends of each armbeing adapted to engage a spoke,

. substantially as set forth.

' their ends on the bar at opposite sides of the arch and at right angles to the wrench-head, substantially as set forth.

3. A vehicle'wrench comprising a springbar arched between its ends, adjustable jaws sliding on the arched part of the bar, and arms mounted between their ends on the bar at op posite sides of the arch and at right angles to the said jaws, substantially as set forth.

4. A vehiclewrench comprising a bar, a

angles thereto, and a spring secured to the bar and to one end of said arms and drawing it toward the wrench-head, substantially as set forth.

5. A Veh'icle-wrenehcornprising the arched bar, adjustable nutreceiving jaws on said arched portion, arms mounted between their ends on said bar at right angles tovsaid jaws and recessed at both ends to engage the adjacent sides of two spokes, and a spring drawing one arm toward the said jaws, snbstantiall y 3 5 as set forth.
